Assuming we only need cardio, I would not spend 1000$ on a TLM103 for just voiceover... To stay with static mics, I would get (and do the tiny capacitor mod) a P220 AKG or an AT4033 or a senn. MK4, all these for less than 400$ brand new from the shop... (and spend the rest for a good compressor or a mixing channel)
And to stay in that budget, for dynamics, there's plenty of good mics which don't need any mod...
